Question about Unold Lunchbox

...my husband is thrilled with this lunch box. No more eating cold because he is out. A good 30 minutes before lunch, plug in the lunchbox "with power cord, is included" turn on, then food is food, my husband said, "it will be hot". We have had a good experience and would buy it again. Washing up is also super easy. The lunch box also comes with cutlery.
